6L80 2-3 flare up
http://forum.grrrr8.net/showthread.php?t=11475&page=2
My local trans guy recently showed me a 6L80 with a common problem where the input drum has a tiny leak at one of the welds which IIRC can cause flare problems.
Needs the updated pump cover with new style sealing rings
Check for cracks in 3-5-R housing around welds
You can vacuum test the valve body, have seen a lot of worn valve bodies lately.
What 3-5-R clutches are in it? And travel? I shoot for .080-.100
